“Radical? What the heck is a Radical?” you may ask. They’re a small company just north of London, England who make fast cars—very, very fast cars. The Nurburgring is a sort of torture test for high-performance cars. When you think of the fastest laps around it, you probably think Ferrari, Pagani, Bugatti, and so forth.

Did you know Radical has all those names beat? In fact, they have almost everyone beat. For the longest time, they held the title of fastest lap around the ‘Ring – 6 minutes and 48 seconds (6:48) – before the SR8LM was just barely beaten out by a Porsche 911 GT2 in 2017. Despite the go-kart looks, the Radical SR8LM is very much street legal—at least in England.
